1997 Chevy Cavalier mileage: 22,000 The engine races on its own. Also accelerates from about 45 up to 90 mph maximum throttle on its own; brakes don't stop it, have to shift to neutral and turn off ignition switch. Intermittent situation can't prove it to dealer. Sometimes engine will stall while driving 35 to 60 mph. Could this be the cruise control? Have you heard this before?

Yes. The cruise control could cause your problem acceleration on its own. The cause of the engine stalling 35 to 60 mph could be many things. Your car is equipped with a computer controlled engine management system. The computer will store any fault or error codes. Having it scanned will retrieve these codes and pinpoint the malfunctioning component.
